Metallics JSSMSS88 – Frequently Asked Questions
1) Is the JSSMSS88 a cup point set screw, and what does that mean for holding a shaft or bus?
Cup point, yes. The cup end is a hollowed ring that bites into the mating surface and leaves a small indent, which is what you want for locking a collar, pulley, hub, or conductor against a shaft or lug and keeping it from spinning. If you need a non-marring hold on a finished shaft, or you are seating into an existing cone-drilled dimple, a flat, oval, or cone point is the better choice.
2) What driver do I need for the Metallics M8 x 20 set screw?
It is a socket set screw, so it drives with a hex key (Allen wrench) in the internal socket at the end, not a screwdriver or a wrench on the outside. There is no head on this fastener, so it seats fully below the surface of the hub or collar.
3) Are these black oxide steel set screws suitable for outdoor or wet locations?
These are black finish steel, not stainless or galvanized. Black oxide on steel is a dry-location finish and gives very little corrosion protection on its own, so for exterior, damp, or washdown work choose a stainless set screw in the same M8 x 20 size instead.
4) How does the JSSMSS88 come packaged, and how many screws do I get?
These ship 100 screws to a jar, which is the practical quantity for an electrical shop or MRO crib that goes through set screws on lugs, connectors, and mounting hardware rather than buying them a handful at a time.
